CONCRETE-FENGE-POST MOLD.

Specification of Letters Patent.

Application filed. April 27, 1912.

To all whom it may concern:

Be it known that I, Gos'rnv H. Fnnsun, a citizen of the United States,residing at Clark, in the county of Randolph and State of Missouri, haveinvented new and useful Improvements in Concrete Fence Post Molds, ofwhich the following is a specification.

This invention relates to concrete fence post molds and has for anobject to provide a mold of this character which will consist of aplurality of mold sections and means for uniformly holding the sectionscolleclively or detachably connected together in set up positions.

Another object of the invention is to provide a mold which can beconstructed of substantially identical sections.

A still further object of the invention is to provide a mold which willbe strong and durable in construction, eflicient for the purposeintended and inexpensive to manufacture.

In the drawing forming a portion of this application, and in which likeletters of reference indicate similar parts in the several views: Figurel is a perspective view of the mold showing the same set up. Fi 2 is aperspective view of one of the sections. Fig. 3 is a perspective view ofanother section of the mold. Fig. 4 is a horizontal section taken online d-t of Fig. 1.

The mold is preferably constructed of heavy sheet metal and it is shownto include substantially identical sections 1 and 2, the latter beingadapted to lit in the former and being coextensive in length therewith.Each section is provided with walls 4-, 5 and 6, the walls 5 and 6 ofthe section 2 being adapted to engage against the inner sides of thecorresponding walls of the section 1 and to also engage against the wall4 of the section 1 when the mold is in a set up position. All of thewalls of each section are of an increased width from one end toward the0pposite end whereby the companion mold sect-ions will operate toproduce or form a post of an increased diameter toward its lower end.The walls 5 and 6 of the section 1 have their longitudinal edges upsetto present longitudinally extending flanges 7 which are adapted torecelve therebeneath the hooked ends 8 of the adjustable locking orretaining devices 9. Any suitable number of these retaining devices maybe employed as may be found desirable to an operative assemblage andproper association of the companion sections of the mold, it of coursebeing understood that said members are each of a difi erent size so asto correspond with the diflerent transverse diameters of the mold. Thewall 4; of the section :2 of the mold extends slightly beyond theflanges 7 of the section 1 of the mold when both sections are set up.From this construction it is evident that the portions 10 of theretaining members 9 will be brought into effective contact with the wall4 of the said section 2 and thereby effectually operate to hold bothsections properly associated and against longitudinal relativemovements.

In use the mold may be disposed vertically with its small end restingupon a suitable support, after which the concrete in a plastic state maybe poured into the large end of the mold until sufficient amounthas beendistributed within the mold as may be necessary to the manufacture of apost. At the requisite time the mold sections may be separated to permitof the removal of the post.

I claim A mold comprising a section tapered toward one end and providedwith side walls terminating in right angularly-disposed flanges, saidflanges being disposed in converging relation from one end of said section to the other end thereof, a second section tapered throughout toflt within the first section and provided with a flat wall lyingparallel with one of the walls of the first section and disposed beyondthe plane of the flanges, and clamping devices adj ustablelongitudinally of the mold and each having an intermediate bodyoverlying the flat wall and end hooked portions extending over andbeneath the flanges and operable when the clamp is moved in onedirection on the mold to advance the body portion of the clamp againstthe flat wall and to move the second section into lateral engagementwith the first section whereby to cause the free edges of the secondsection to mutually engage one of the walls of the first section.

In testimony whereof I aflix my signature in presence of two witnesses.

GUSTAV H. FENSKE.
